Introduction: The diaphragmatic rupture is a diagnostic and a therapeutic challenge for physicians who have to face the management of polytraumatized patients; there must always be suspicion on traumatic injuries of thoracic or abdominal location. Objective: To inform the diagnostic and therapeutic elements followed in case of diaphragmatic and splenic rupture of traumatic origin. Presentation of the case: 14-year-old male teenager that was admitted for presenting stabbing wound by sharp weapon, with abdominal location and clinical manifestations that allow making the diagnosis of the condition being treated. During surgery, it was found the rupture of the diaphragm, a diaphragmatic hernia and splenic rupture with output of blood into the abdominal cavity. It was conducted the reduction of the hernia, the suture of the diaphragm and the removal of the spleen due to the state of the organ during the surgery. Conclusions: Post-traumatic diaphragmatic rupture is an entity that it is most often seen in pediatric patients. The clinical examination aided by imaging studies is vital for its diagnosis, early treatment and to avoid complications. It is important to maintain a high index of suspicion to face this rare entity, but not so rare in the pediatric age group. The patient had a favourable evolution and he was discharged of the surgery service after 10 days of hospitalization(AU)

Ruptura diafragmatica postraumatica en pediatria: A proposito de un caso / Post traumatic diaphragmatic rupture in children: Case report

La ruptura diafragmática es una entidad relativamente infrecuente en pediatría que se puede presentar como consecuencia de un traumatismo de alto impacto. Solo entre el 25% y el 50% de los casos es detectado en la evaluación inicial del paciente, lo que aumenta el riesgo de complicaciones. En este trabajo, se presenta el caso de una paciente asintomática, de 8 años de edad, que, tras un accidente vehicular y la evaluación inicial en otro centro, fue derivada a nuestra Institución para el control evolutivo. A las 36 horas del ingreso, presentó hipoventilación pulmonar izquierda. La tomografía demostró un ascenso intratorácico del ángulo esplénico del colon y asas de intestino delgado. Se efectuó la exploración y el tratamiento quirúrgico. Los controles radiográficos diferidos no mostraron signos de recidiva.

Diaphragmatic rupture is a relatively uncommon entity in pediatrics that can occur as a result of a high-impact trauma. Only between 25 and 50% of the cases are detected in the initial evaluation of the patient, which increases the risk of complications. This paper presents the case of an asymptomatic 8-year-old patient who was referred to our institution after a vehicular accident. A day and a half after admission, a left pulmonary hypoventilation was detected. Computed tomography scan showed intrathoracic elevation of the splenic angle of the colon and the small bowel. Surgical exploration and treatment were performed. Deferred radiographic controls showed no signs of relapse.

Análise retrospectiva de 103 casos de lesão diafragmática operados em um centro de trauma / Retrospective analysis of 103 diaphragmatic injuries in patients operated in a trauma center

RESUMO Objetivo: analisar os fatores associados ao óbito em pacientes com lesão diafragmática atendidos em hospital de referência para o trauma. Métodos: estudo retrospectivo de pacientes com lesão do diafragma atendidos no Hospital Risoleta Tolentino Neves da Universidade Federal de Minas Gerais entre janeiro de 2010 e dezembro de 2014. Foi utilizado o Banco de Registros de Trauma Collector® (MD, USA). Utilizaram-se dados demográficos, localização da lesão diafragmática, lesões associadas de outros órgãos, número de lesões associadas, tipo de abordagem terapêutica, complicações e o escore de gravidade Injury Severity Score (ISS). A variável de interesse foi a ocorrência de óbito. Resultados: foram identificados 103 pacientes e a incidência de óbito foi de 16,5%. Lesões penetrantes ocorreram em 98% dos pacientes. Em análise univariada a mortalidade foi maior em pacientes cujo tratamento foi não operatório, sem rafia (p=0,023), e menor em pacientes submetidos à rafia diafragmática (p<0,001). O aumento do número de lesões associou-se ao aumento da incidência de óbitos (p=0,048). Em análise multivariada, ISS>24 (OR=4,0; p=0,029) e rafia do diafragma (OR=0,76; p<0,001) associaram-se à mortalidade. Conclusão: os achados indicam que a ruptura traumática do diafragma raramente se apresenta como lesão isolada, estando associada frequentemente à lesão de outros órgãos, especialmente fígado e vísceras ocas. Pode-se afirmar que a mortalidade foi mais elevada entre aqueles com ISS>24.

ABSTRACT Objective: to analyze the factors associated with death in patients with diaphragmatic injury treated at a trauma reference hospital. Methods: we conducted a retrospective study of patients with diaphragm injury attended at the Risoleta Tolentino Neves Hospital of the Federal University of Minas Gerais, between January 2010 and December 2014. We used The Collector® database of trauma records (MD, USA). We gathered data on demographics, location of the diaphragmatic lesion, site and number of associated lesions, type of therapeutic approach, complications and Injury Severity Score (ISS). The variable of interest was the occurrence of death. Results: we identified 103 patients and mortality was 16.5%. Penetrating lesions occurred in 98% of patients. Univariate analysis showed a mortality higher in patients whose treatment was non-operative, without closing of the defect (p=0.023), and lower in patients submitted to diaphragmatic suturing (p<0.001). The increase in the number of lesions was associated with an increase in mortality (p=0.048). In multivariate analysis, ISS>24 (OR=4.0, p=0.029) and diaphragmatic suturing (OR=0.76, p<0.001) were associated with mortality. Conclusion: The findings indicate that the traumatic rupture of the diaphragm rarely presents as an isolated lesion, being frequently associated with injuries of other organs, especially the liver and hollow viscera. Mortality was higher among those with ISS>24.

Repair of penetrating pericardial and diaphragmatic injury with cormatrix® patch in a case of suicide attempt

Abstract The authors report the case of a suicide attempt. A 59-year-old man with self-inflicted penetrating chest trauma underwent emergency cardiothoracic surgery. Pre-operative computed tomography scan showed critical proximity between the blade and the right ventricle. Intraoperative findings showed a pericardial laceration and a huge diaphragmatic lesion with heart and abdominal organs integrity. The diaphragm muscle was repaired with a CorMatrix® patch, an acceptable alternative to the traditional synthetic mesh avoiding infection and repeated herniation.

Hérnia diafragmática direita associada à hepatotórax assintomático com correção de cirurgia precoce / Right diaphragmatic hernia associated to asymptomatic hepatotorax with early surgical correction

A ruptura diafragmática decorrente de lesão traumática é uma entidade rara, secundária ao trauma fechado ou penetrante. O diagnóstico é difícil, o que pode fazer com que o tratamento cirúrgico seja retardado, acarretando um aumento da morbimortalidade. Os autores relatam o caso de paciente de 39 anos, do sexo feminino, vítima de trauma com alto impacto devido a atropelamento. Após 13 dias de internamento, radiografia de tórax permaneceu com obliteração do seio costofrênico e velamento do terço inferior do hemitórax direito. Tomografia computadorizada de tórax evidenciou grande parte do fígado em posição intratorácica, sugerindo a possibilidade de ruptura torácica e hepatotórax. O tratamento foi realizado por meio de uma toracotomia anterolateral direita com rafia do defeito diafragmático e redução do saco herniário. Sendo assim, apesar de raro, o hepatotórax é uma entidade que deve sempre ser lembrada em pacientes vítimas de traumas torácicos de alta intensidade.

The diaphragmatic rupture due to traumatic injury is a very rare entity that may be due to blunt or penetrating trauma. Diagnosis is difficult and therefore surgical treatment may be delayed, resulting in increased morbidity and mortality. The authors report the case of a 39-year-old patient, female, who was victim of a high-impact trauma due to trampling. Standard chest X-ray did not showed positive evolution after 13 days of hospitalization, with costophrenic angle obliteration and opacification of the lower third of the right hemithorax. It asked then a chest CT scan that showed much of the liver in intratoracic position. The treatment was carried out successfully by a right anterolateral thoracotomy with suture and correction of diaphragmatic hernia. Thus, although rare, hepatotorax is an entity that should always be remembered in trauma patients with high impact.

Repair of diaphragmatic injury and placement of tube thoracostomy during right upper quadrant peritonectomy / 부인종양

OBJECTIVE: Patients with advanced or recurrent ovarian cancer often have metastatic disease in the upper abdominal region, especially to the right hemidiaphragm, which requires diaphragmatic resection in order to achieve optimal cytoreduction. The aim of this surgical video is to demonstrate repair of a diaphragmatic injury and placement of tube thoracostomy during right upper quadrant peritonectomy in a patient with recurrent ovarian cancer. METHODS: This is the case of a 45-year-old woman presented with platinum sensitive recurrent ovarian cancer. Abdomen computed tomography also confirmed peritoneal carcinomatosis and pelvic recurrent mass. HIPEC was administered after complete cytoreduction including bilateral upper quadrant peritonectomy, during which diaphragmatic injury occurred near the central tendon and pleural cavity was entered. We inserted a chest tube through the 6th intercostal space in the anterior axillary line in order to prevent postoperative massive pleural effusion. Diaphragmatic defect was closed primarily after the tube placement. The chest tube was withdrawn on the third postoperative day and the patient was discharged on postoperative day 25 without any complications. RESULTS: The central tendon of diaphragm is the most vulnerable part for lacerations. Diaphragmatic repairs could be performed by various techniques; interrupted or continuous, locking or non-locking sutures, with either permanent or absorbable materials. In our view, all of the techniques provide similar results and surgeons can choose any of them as long as they are comfortable with the procedure. CONCLUSION: In most cases, these lacerations can be repaired primarily without necessitating tube thoracostomy. However, performance of HIPEC can cause massive pleural effusions which can lead to significant pulmonary morbidity. Therefore, retrograde placement of the chest tube under direct vision is quite straightforward when the diaphragm is opened.

Analysis of natural history of the diaphragmatic injury on the right in mice / Análise da evolução natural dos ferimentos diafragmáticos à direita em ratos

Objective: to evaluate natural evolution of right diaphragmatic injury after the surgical removal of a portion from hemi diaphragm. Methods: the animals were submitted to a surgical removal of portion from right hemi diaphragm by median laparotomy. The sample consists of 42 animals being 2 animals from pilot project and 40 operated animals. And the variables of the study were herniation, liver protection, healing, persistent diaphragm injury, evaluation of 16 channels tomography and the variables "heart rate" and "weight". Results: we analyzed 40 mice, we had two post-operative deaths; we had 17 animals in this group suffered from herniation (42.5%) and 23 animals didn't suffer from herniation (57.5%). Analyzing the tomography as image method in the evaluation of diaphragmatic hernia, we had as a method with good sensitivity (78.6%), good specificity (90.9%), and good accuracy (86.1%) when compared to necropsy. Conclusion: there was a predominance of healing of right hemi diaphragm, the size of initial injury didn't have influence on occurrence of the liver protection or hernia in mice.

Objetivo: avaliar a evolução natural do ferimento diafragmático à direita após a retirada cirúrgica de uma porção do hemidiafragma. Métodos: os animais foram submetidos à ressecção de uma porção do hemidiafragma à direita através da laparotomia mediana. Foram operados 40 ratos. As variáveis analisadas foram: herniação, proteção hepática, cicatrização, lesão persistente do diafragma, avaliação da tomografia computadorizada, frequência cardíaca e peso. Resultados: foram analisados 40 ratos. Houve duas mortes no pós-operatório. Dezessete animais tiveram herniação (42,5%) e 23 (57,5%), não. Analisando emprego da tomografia computadorizada na avaliação da hérnia diafragmática, tivemos um método com boa sensibilidade (78,6%), boa especificidade (90,9%) e boa acurácia (86,1%) quando comparados com a necrópsia. Conclusão: houve predomínio de cicatrização do hemidiafragma à direita e o tamanho da lesão inicial não influenciou na ocorrência de proteção hepática ou hérnia em ratos.

Traumatic asphyxia with diaphragmatic injury: a case report

Traumatic asphyxia, or Perthe's syndrome, is a rare clinical syndrome characterized by cervicofacial cyanosis, petechiae, subconjunctival hemorrhage, neurological symptoms, and thoracic injury. It affects both adults and children after blunt chest traumas. The diagnosis of this condition is based mainly on the specific clinical signs, which should immediately bring to mind the severity of the trauma, the various probable types of pulmonary injuries, and the need for screening and careful assessment of other organs that might also be injured. In this report, we describe the case of a 39-year-old male who developed traumatic asphyxia after severe blunt chest trauma during his work at a construction site. The patient had multiple injuries to the chest, abdomen, head and neck, which were treated conservatively. An associated diaphragmatic injury was successfully treated by video-assisted thoracic surgery. This patient is one of five patients who were admitted to Saqr Hospital in the United Arab Emirates, diagnosed with traumatic asphyxia, and treated by mechanical ventilator, supportive measures, and fiberoptic bronchoscopy, for both diagnostic and therapeutic indications, in our unit in the period between July 2006 and June 2013. As traumatic asphyxia is a systemic injury, careful assessment of the patient and looking for other injuries is mandatory. Treatment usually involves supportive measures to the affected organs, but surgical intervention may sometimes prove to be an important part of the treatment. Bronchoscopy should be performed for diagnostic and therapeutic reasons because of the associated pulmonary and possible tracheobronchial injuries

Natural history of extensive diaphragmatic injury on the right side: experimental study in rats / História natural do ferimento diafragmático extenso à direita: estudo experimental em ratos

OBJECTIVE: To evaluate the natural healing of the rat diaphragm that suffered an extensive right penetrating injury. METHODS: Animals were submitted to an extensive penetrating injury in right diaphragm. The sample consisted of 40 animals. The variables studied were initial weight, weight 21 days after surgery; healing of the diaphragm, non-healing of the diaphragm, and herniated abdominal contents into the chest. RESULTS: Ten animals were used as controls for weight and 30 animals were operated. Two animals died during the experiment, so 28 animals formed the operated group; healing of the diaphragm occurred in 15 animals (54%), 11 other animals showed diaphragmatic hernia (39%) and in two we observed only diaphragmatic injury without hernia (7%). Among the herniated organs, the liver was found in 100% of animals, followed by the omentum in 77%, small bowel in 62%, colon in 46%, stomach in 31% and spleen in 15%. The control group and the diaphragmatic healing subgroup showed increased weight since the beginning of the study and the 21 days after surgery (p <0.001). The unhealed group showed no change in weight (p = 0.228). CONCLUSION: there is a predominance of spontaneous healing in the right diaphragm; animals in which there was no healing of the diaphragm did not gain weight, and the liver was the organ present in 100% the diaphragmatic surface in all rats with healed diaphragm or not. .

OBJETIVO: avaliar a cicatrização natural do diafragma de ratos que sofreram um ferimento penetrante extenso à direita. MÉTODOS: os animais sofreram uma lesão penetrante extensa no diafragma direito. A amostra foi composta por 40 animais. As variáveis estudadas foram peso inicial e em 21 dias de operados; cicatrização do diafragma, não cicatrização do diafragma e conteúdo herniado do abdome para o tórax. RESULTADOS: dez animais constituíram o grupo controle para o peso e 30 animais foram operados. Dois animais morreram durante o experimento, sendo assim, 28 animais constituíram o grupo de operados; ocorreu a cicatrização do diafragma em 15 animais (54%), outros 11 animais apresentaram hérnia diafragmática (39%) e por fim em dois animais observamos somente lesão diafragmática sem hérnia (7%). Analisando os órgãos herniados, encontramos o fígado em 100% dos animais, seguido pelo omento em 77%; delgado em 62%; cólon em 46%; estômago em 31% e baço em 15%. Os grupos controle e de cicatrização do diafragma apresentaram acréscimo significativo de peso do momento inicial para o momento 21 dias (p<0,001). O grupo não cicatrizado não apresentou alteração de peso (p=0,228). CONCLUSÃO: há predomínio da cicatrização espontânea no diafragma à direita, os animais em que não houve a cicatrização do diafragma não aumentaram de peso, e o fígado foi o órgão 100% presente na superfície diafragmática em todos os ratos com cicatrização ou não do diafragma. .

Post-traumatic synchronous twin inter-muscular abdominal and diaphragmatic hernias: A rare presentation.

Simultaneous occurrence of traumatic abdominal wall hernia (TAWH) and traumatic diaphragmatic hernia (TDH) is uncommon. Our report documents the rare delayed presentation of simultaneous occurrence of TAWH and TDH in a patient who sustained a bicycle handlebar injury as a consequence of the bicycle he was riding colliding with a motorbike in a road-traffic accident. Excellent outcome could be achieved in this patient with surgical repair without requiring the use of a mesh.

Toda lesão do diafragma por ferimento penetrante deve ser suturada? / Must all diaphragmatic penetrating wounds be sutured?

Os ferimentos da região tóracoabdominal podem cursar com ferimentos diafragmáticos em até 48% dos casos. Lesões associadas ao trauma diafragmático, estão presentes na maioria das vezes, o que facilita o diagnóstico da lesão diafragmática e em consequência impõe o tratamento operatório. Porém em 8 a 10% dos casos, as lesões diafragmáticas são isoladas e por apresentarem pouco ou nenhum sintoma, estas lesões podem passar despercebidas. Nestas situações, o diafragma poderia ser tratado de modo conservador, sem a sutura do mesmo? Após a realização de trabalhos experimentais com animais e de analisar a literatura, concluímos que ainda não podemos afirmar com certeza de que é possível não suturar um ferimento diafragmático.

Wounds to the abdominal-thoracic region are associated with diaphragm wounds in up to 48% of cases. Lesions secondary to diaphragm trauma are present in the majority of cases, facilitating the diagnosis of diaphragm lesion and subsequent surgical management. However, diaphragm lesions are isolated in 8 to 10% of cases and because they present few or no symptoms may be overlooked. In such situations, can the diaphragm be treated conservatively without suturing? Based on experiments in animals and a review of the literature, we concluded there is currently insufficient evidence to affirm that diaphragm injuries require no suturing.

[Prevalence of intra abdominal injuries due to penetrating trauma in Gorgan, Iran [2002-07]]

Trauma is the most common cause of death in all individuals between 1 and 44 years and the third most common cause of death regardless of age. The abdomen is the third most commonly injured region of the body. Some intra abdominal organ injured more than others, related to mechanism of injury, size and location of organ in abdominal cavity. This study was carried out to determine the prevalence of intra abdominal injuries due to penetrating trauma. This retrospective descriptive study was done on 114 patients admitted to 5 Azar hospital in Gorgan, Iran due to penetrating abdominal trauma during 2002-07. Gender, age, type of injury causes of trauma and hospitlalization period were obtained form patients files. 92.1% of patients were male. The mean age of subjects was 24.8 years [9-70 years] with highest frequency between 20-24 years. Two [1.8%] deaths directly related to abdominal stab wounds related to hemorrhagic shock. The most common cause of penetrating abdominal injury was knife wound [78.9%]. The mean time spent in hospital was 4.6 +/- 2.8 days. In 53 patients, cause of trauma were either related to pentration into peritoneum or passing through in. Small intestine injuries [14%], rupture of diaphragm and concurrent lung injuries [7%] were the common damage organs. This study showed that the knife was the main cause of abdominal penetrate trauma and peritoneum was the most common damage tissue

Can lung volumes and capacities be used as an outcome measure for phrenic nerve recovery after cardiac surgeries?

Phrenic nerve is the main nerve drive to the diaphragm and its injury is a well-known complication following cardiac surgeries. It results in diaphragmatic dysfunction with reduction in lung volumes and capacities. This study aimed to evaluate the objectivity of lung volumes and capacities as an outcome measure for the prognosis of phrenic nerve recovery after cardiac surgeries. In this prospective experimental study, patients were recruited from Cardio-Thoracic Surgery Department, Educational Hospital of College of Medicine, Cairo University. They were 11 patients with right phrenic nerve injury and 14 patients with left injury. On the basis of receiving low-level laser irradiation, they were divided into irradiated group and non-irradiated group. Measures of phrenic nerve latency, lung volumes and capacities were taken pre and post-operative and at 3-months follow up. After 3 months of low-level laser therapy, the irradiated group showed marked improvement in the phrenic nerve recovery. On the other hand, vital capacity and forced expiratory volume in the first second were the only lung capacity and volume that showed improvement consequent with the recovery of right phrenic nerve [P value <0.001 for both]. Furthermore, forced vital capacity was the single lung capacity that showed significant statistical improvement in patients with recovered left phrenic nerve injury [P value <0.001]. Study concluded that lung volumes and capacities cannot be used as an objective outcome measure for recovery of phrenic nerve injury after cardiac surgeries

Lesión diafragmática durante la laparoscopia urológica transperitoneal / Diaphragmatic injury during transperitoneal urological laparoscopic surgery

Introduction: Capnothorax is a rare complication of urologic laparoscopy. However with the increasing use of this technique in a variety of urological procedures, this rare complication is a potential risk. Material and Methods: We analyzed a total of 786 urological procedures performed by transperitoneal laparoscopy in our center. All procedures were performed by the same surgeon: 213 adrenalectomy, 181 simple nephrectomies, 143 lymphadenectomies, 118 radical nephrectomies, 107 partial nephrectomies and 24 nephroure-terectomy. Results: A total of 6 patients (0.7 percent) present diaphragmatic lesions. The diaphragmatic repair was performed totally intracorporeal. One patient required the placement of a pleural drainage. No patient presented complications associated with diaphragmatic injury. Conclusion: Repair of diaphragmatic injury during transperitoneal laparoscopy can be performed successfully by this route. This technique is feasible, reproducible and reliable. This is the largest series reported by a single center.

Introducción: El capnotórax es una complicación infrecuente de la laparoscopía urológica. No obstante, con el uso cada vez mayor de esta técnica en una gran variedad de procedimientos urológicos, esta infrecuente complicación se presenta como un riesgo potencial. Material y Métodos: Se analizaron un total de 786 procedimientos urológicos realizados en forma laparoscópica por vía transperitoneal en nuestro centro. Todos los procedimientos fueron realizados por el mismo cirujano: 213 adrenalectomías, 181 nefrectomías simples, 143 linfadenectomías, 118 nefrectomías radicales, 107 nefrectomías parciales y 24 nefroureterectomías. Resultados: Un total de 6 pacientes (0,7 por ciento) presentaron lesiones diafragmáticas. La reparación diafragmática fue efectuada totalmente en forma intracorpórea. Un solo paciente requirió de la colocación de un drenaje pleural. Ningún paciente presentó complicaciones asociadas a la lesión diafragmática. Conclusión: La reparación de las lesiones diafragmáticas ocurridas durante la laparoscopía transperitoneal puede ser efectuada exitosamente por esta misma vía. Esta técnica es factible, reproducible y confiable. Esta es la serie más grande reportada por un solo centro.

A importância da propedêutica em ferimentos tóraco-abdominais à esquerda por arma branca / The importance of propedeutic on left thoracoabdominal region stab wounds

O diafragma pode ser lesado tanto nos traumas contusos quanto nos penetrantes. A incidência de lesão diafragmática nas feridas penetrantes na região tóraco-abdominal esquerda por arma branca varia de 20 a 24. A porcentagem de assintomáticos pode atingir 30 e a lesão, usualmente, é clinicamente despercebida. A maioria dos casos apresenta alterações radiológicas mínimas. A principal complicação é a hérnia estrangulada, que aumenta a taxa de mortalidade de 3 a 7 para 25 a 30 . O alto índice de suposição é o fator mais importante para o diagnóstico. O uso da videolaparoscopia diagnóstica e terapêutica, em casos selecionados, diminuiu o número de laparotomias brancas. A baixa sensibilidade diagnóstica associada à clínica e aos procedimentos radiológicos requer abordagem intervencionista para que as lesões diafragmáticas sejam rapidamente diagnosticadas e evitadas futuras complicações.

Diaphragmatic rupture occurs after blunt or penetrating wound. The incidence of diaphragmatic rupture in patients with penetrating wounds in the left thoracoabdominal area varies from 20 to 24. The rupture is observed in up to 30 of asymptomatic patients and is not usually detected by physical exam. In most cases, radiological investigation shows minimal alterations. The main complication is the strangulated hernia, which rises the mortality rate from 3-7 to 25-30 . A high grade of clinical suspicion is the main contributor to elucidate the diagnostic. The use of diagnostic and therapeutic videolaparoscopy has downsized the number of white laparotomies. Considering the low sensitivity of clinical exam and radiological investigation, an aggressive approach to diagnose diaphragmatic lesions and avoid future complications is recommended.

Traumatic rupture of diaphragm with flail chest mimicking tension hydropneumothorax.

Traumatic rupture of diaphragm though not rare, presents as complication of penetrating and blunt injuries of chest and abdomen. Preoperative diagnosis of diaphragmatic injury is difficult because of the complex shape of the thin diaphragmatic muscle, the horizontal in-plane orientation of one diaphragmatic dome, and the often associated traumatic abnormalities in the lung bases. Failure to detect this underlying injury is associated with significant morbidity and mortality because of delayed visceral herniation, strangulation or both. We report a case of left-sided post traumatic rupture of diaphragm presenting as tension hydropneumothroax following a road traffic accident. It was managed as tension hydropneumothorax during initial resuscitation by intercostal tube drainage. Lack of improvement in the clinical condition led to the suspicion of diaphragmatic rupture. The patient was managed successfully by operative repair of diaphragm and manual reduction of hernial contents

Empiema posterior a trauma tóraco-abdominal / Empyema after thoraco-abdominal trauma

Evaluar la posibilidad de empiema en el trauma tóraco-abdominal con lesión de viscera hueca y diafragma. Estudio retrospectivo, descriptivo y transversal, realizado en un período comprendido entre los años 2002 y 2008. De un total de 304 pacientes ingresados con el diagnóstico de trauma tóraco-abdominal, se estudiaron 40 historias clínicas de aquellos que presentaron lesión de diafragma, en las cuales se evaluó el tratamiento efectivo a la lesión toracica y su seguimiento. Hubo 39 pacientes del sexo masculino (97,5 por ciento) y 1 femenino (2,5 por ciento), con edades comprendidas entre 13 y 60 años (promedio 27,9 años). El mecanismo de lesión más frecuente fue las heridas por arma de fuego con 33 casos (82,5 por ciento); arma blanca con 6 (15 por ciento) y trauma cerrado con 1 caso (2,5 por ciento). En todos los pacientes se dejo un drenaje torácico a través de una toracotomía mínima. En 3 de ellos (7,5 por ciento) se realizó la exploración del tórax a través de una toracotomía. Se reportaron 3 casos de empiema, todos en el grupo de toracotomía mínima como manejo de la lesión torácica. Lesiones de viscera hueca, inestabilidad hemodinámica y un ATI > 30 fueron los factores de riesgo más frecuentes asociados a la formación del empiema. En un trauma tóraco-abdominal con lesión de diafragma y viscera hueca, la contaminación del tórax es posible, por lo que sólo un drenaje torácico podría ser insuficiente para una adecuada limpieza de la cavidad pleural.
